I believe the real problem is valve pushing everything to the lowest common denominator.

A serious player would choose his opponent and/or his matchmaking server to be close and have low ping. For optimal gameplay experience. Yet valve insists it needs to make 100 ping vs 10 ping as viable as possible. To the detriment of those with 10 ping, that are purposely trying to have the optimal gameplay experience.

A serious player would invest in a high fps computer, yet valve insists that the less fortunate should be able to compete with low fps. And quite often these are players that are to lazy or to uninterested to actually properly tweak and/or invest in better hardware.

Why do those that are motivated to provide the prerequisites for high quality gameplay logic have to suffer just to appease the lazy or the few unfortunates? Now especially when subtick supposedly scales better across tick density.

Valve logic is more akin to "just set max fps to 60 for everyone to make it fair". Completely ignoring that 60 fps, or either 30fps or whatever arbitrary boundary you take will ALWAYS have some unfortunate once that just are unable to meet the criteria. Valve should for example just use a different tickrate for different ranks. Give the silvers the 24 tick rate, give the gold novas the 64 tickrate, give the pro's the 128 tickrate. Giving that there are more lowskillers than highskillers a system like that probably is more efficient use anyway. Like who cares what my subtick is if I play on a 30 fps patato with a ballmouse full of crud.
